What statute requires that a sender's message contains clear notice that it is an advertisement?

The CAN-SPAM Act is designed to regulate commercial email messages, ensuring that recipients have certain protections against spam. One of its key provisions requires that any sender of a commercial email include clear notice that the message is an advertisement. This is crucial because it allows recipients to easily identify promotional content in their inboxes, promoting transparency in electronic communications. By mandating this clear labeling, the statute aims to prevent deceptive practices and helps recipients make informed decisions about the emails they choose to engage with.

The other statutes mentioned do not specifically address the requirements for labeling advertisements in messages. The Interstate Land Sales Full Disclosure Act focuses on the sale of land, the Do Not Call statute relates to telemarketing calls, and the Junk Fax Prevention Act is concerned with unsolicited faxes, each serving different regulatory purposes rather than addressing email advertisements specifically.
